Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Abilene, but one thing the team at Abilene Air-Tech Inc wants you to be able to count on is your heating and cooling system. Having a cozy home isn’t a seasonal thing, it’s something you expect all year. When your furnace is having trouble you may think that means a furnace repair can be expected in your future. That may not be the case. If your furnace hasn’t been its usual, stable self as of late, there are a couple of things a homeowner can do before calling in the experts at Abilene Air-Tech Inc. Check the Thermostat We have had calls where the only thing we did was switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily forget to flip the switch, telling your heating and cooling system what you want it to do. One thing to look at while you’re at the thermostat is the battery. Most digital thermostats have a low battery warning, but if it’s been some time since you’ve changed batteries it may be time for a change. It’s another simple fix that could save you a repair call. Check the Filter A dirty air filter can create all sorts of problems. Not only will a dirty filter cripple your system’s efficiency and block air flow, it could also cause an unexpected breakdown. Changing the filter in your heating and cooling system is simple and it can play a big role in keeping your system running at its best. Check the Switches The first switch you’ll want to check is the breaker for your furnace. Occasionally a problem can be as simple as a tripped breaker or blown fuse. Check the Vents A common misconception is that a homeowner should seal the vents in unused rooms. This could actually lead to a furnace repair in the future. Closed vents create higher pressure throughout your duct system and cause your system to work harder than it needs to. If you’ve been through our troubleshooting tips and you’re still having issues the team at Abilene Air-Tech Inc are always there for you to make sure all of your home comfort needs are met.
